  • Publication number: 20250140642
    Abstract: A thermoelectric cooler (TEC) is positioned to move heat away from a hot spot on a semiconductor chip and toward a dielectric substrate. This approach to thermal management is particularly effective when used in conjunction with a buried rail and back side power delivery. The TEC may be in a layer that contains solder connections be between two device layers an IC package. Alternatively, the TEC may be in a metal interconnect structure over the semiconductor substrate such as in a passivation stack at the top of the metal interconnect structure. TECs at either of these locations may be formed by wafer-level processing.

  • Publication number: 20250138926
    Abstract: A Reliability, Availability and Serviceability (RAS) offload Post-Package Repair (PPR) request system includes a memory system coupled to a Baseboard Management Controller (BMC) device and a Basic Input/Output System (BIOS) subsystem. The BMC device identifies an error in the memory system, retrieves error information associated with the error, uses the error information to generate a Post-Package Repair (PPR) request, and stores the PPR request in a BMC database provided in the BMC device. During an initialization process that occurs subsequent to storing the PPR request in the BMC database, the BMC device retrieves the PPR request and stores it in a shared buffer subsystem. During the initialization process, the BIOS retrieves the PPR request from the shared buffer subsystem, stores the PPR request in a BIOS database provided in the BIOS subsystem, and performs PPR operations on the memory system based on the PPR request stored in the BIOS database.
